I think it would depend on how you define bad sex. I would define it as sex in which one or both are hurt or forced into it. That would qualify as bad sex. If however both enjoy it, even if it were not as good as it could be, then I can't see how you could ever call it bad sex. I have never, ever experienced bad sex. May not always have been great but still it is so much better than doing it alone.

Haha, you cheeky bugger!Mind you, I guess doing it on your own is mainly about the orgasm, and from the amount of fuss women make when they come, their orgasms must be a heck of a lot better than mine!
